Surrounding the stationary membersl arerockingplates 21, provided wit-h open-` ings 22 of substantially the samejshape. as, but slightly larger than, the stationary members 10. Secured to the lower Vface of said rocking plates at the ends thereof are substantially U-shaped mounting brackets vv23 which are Ladapted to receive theshafts 12 whereby the rockingplates may be vmounted thereon. The brackets`23 are provided with alined openings 24 'to receive a bolt ori'pin 25, whereby the plates 21 may be detachably The upper and lower' secured to theshafts 12'.

Acorrugations', or the' like. The ribs'on the rupper surface of the'plate serve to break up the fire'when the plate 21 is rocked,'and fur'- ther serve as'strengthening means to prevent the breaking or lwarping ofthe plates. The ribs on the lower face also serve as additional strengthening means.4 The ribs on the up-V per face of the plate arerounded orbeveled as indicated at 2-7 toy allow a hook or poker to lfreely pass over the same without catching when braking the fire from theV top. The

,y Y ribs are angularly disposed, preferably fob- 1ique1y,`^with relation to the rocking plate.y

vBy'so disposing the ribs on the rocking plate the angularl disposed fingers 19 may bere-r ceived there etween, and the ribs present` Ving ears 30V securedto the lower faces ofthe rocking plates 21.

An elbow 331s threaded as. :1t-34 into the distrbuting pipe and communicates with a Supply pipe 35- 1 As Indicated w in Figurel, the grate maybe made `up' ofal plurality'of individual sections as heretofore described. The number of in-v divxdual units may vary according to the size of the iire'box and the purpose to which the device is tobe put. i

The rocking platesv 21 are mounted on the shafts-12 by means -of the Y depending U-shaped mountingl brackets 23 and are secured thereto by inserting the pin 25 into the openings 24. By thisarrangement the rocking plates are adapted-to rock upon the shafts 12 and are readily removable therefrom in case Vof breakage.
